摘要	The deformation structure of single crystal copper during 4 passes equal channel angular pressing (ECAP) through route Bc was investigated by electron backscatter diffraction (EBSD) and XRD, and the mechanical properties of the deformed material were measured. The results show that the macroscopic orientation of the single crystal under low pass deformation does not change. After 2 passes, an orientation-ordered shear band appears and inclines within the range of 15°~20° in the ED direction, with a deformed texture {111} on the grains; After 4 passes, the angle between the shear band and the ED direction is constant, while the inclined direction is opposite to that of the 2 passes, the texture of the material is still {111} texture, and no large angle grain boundary is present; After 5 passes, the tensile strength increases from 168 MPa to 395 MPa, and the elongation decreases from 63% to 26.5%, the material hardness increases from 600 MPa to 1250 MPa, and then tends to change little. Because of the accumulation of dislocations, the plastic deformation ability of the material becomes deteriorated, and the necking area increases. ECAP has a positive effect on increasing the strength of single crystal copper with unbroken grains. © 2018, Science Press.
